. To (all it may concern: I

- citizen of? the United States, 'residin 'Bro'oklyn, in the county of Kings and tate Be it known that I, EnNEsT Nrnnorr, a at of New York, have invented certain new and useful Improvements in Submarine Boats;

andl do hereby declare the followingito be a submarine boats, and more means for controlling the dept of the plunge.

full, clear, and exact descri tion of the invention, such as will enable ot ers skilled in the 2 art to which it appertains to make and use the same.

This invention relatesto improvements in articularly to and for maintaining a balancedcondition of the boat. p g p "The object in v1ew, is the provlsion of a means for automatically governing the uanv tity of ballast carried by the submarine oat;

A'further objectis thearranging of the whereby the depth of the plunge may be govemed.

parts for maintaining an equal balance and at the same time forautomatically governing the intake and discha'r e of the'ballast. o

With these and furt er objects in View the invention comprises certain novel constructions, combinations, and arrangements of a parts, as w1ll be .3

hereinafter fully described andclaimed, a I In the accompandrawings, liigure- 1 represents a view in si e elevation of a submarine boat, parts being broken away for disclosing the interior structure. Fig. 2 re reot line 22 of Fl 11 and looking in the rection V indicat'ed y the arrow, parts being j shown in elevation; Fig. '3 represents'a detaillvertical section takenthrough one of the 4 cylinders; illustratin the valve actuating v iston elevation. ig; 4 represents an enarged detail view, partly in section and "partly in elevation, of one of the balance:

I rovide such a compartment or chamber, as indicated at e drawings by-numerals, l

the strength of the spring 14 being employe The inner head of the cylinder 12 is prefer- 2, which compartment or chamber may be of any required size and is preferably disposed immediately. above the keel of the vessel 1-.

manycells. or'srnall compartments as may be found desirable, and the said chamber may be made of as great length and size as re;

uired for accomplishing the results desired.

t a suitable point in the wall of the vessel 1 is arranged a valve-o ening communicating between the outside 0 said vessel and the interior of the chamber or com artment 2, said valve-opening being closed y the valve 3, provided with a stem 4 ands-suitable operatmg wheel or handle 5, adapted to be actuated for elevating the valve for. permitting the entrance-of water ballast to the chamber 2 when desired. A pipe 6 extends from the top of the chamber 2 and is. closedby the valve, 7 said valve being designed [to be opened manually for permitting the discharge 0t air from the chamber 2 when the, valve '3 is opened for admitting water; After the desired quantit of water has been admitted the valve 3 is esigned to be closed and the valve 7 is also designed to be closed r v At each side of the vessel 1- is arranged a compressed-air reservoir 8, eachhof which is preferably constructed relatively narrow and conforming to the contour of the side-wall of the vessel, whereby only aminimum amount of space is occupied by the said reservoir. A pipe 9 leads from each of the reservoirs 8 and extends into the chamber 2. A valve 10 is interposed in the length of each of the pipes 9, I

the vessel 1. The cylinder 12 inclosesa pis T ton 13, to which the stem 11 isconnected,"

and a coil or other suitable spring 14' surroundsthe stem 11 and is'disposed between the piston 3 and the inner head of the cyl' der 12, so as to retain the piston 3 normallygiii its outer position, in which position the'valve 10 is held closed. The outer end of the cvlinder 12 is formed with apertures 15 15 for admitting water from the exterior of the vessel 1, the spring 14 being capable of resisting the pressure of the exterior water up to a cer-.\

tain point, which may be. predetermined b 'IIO.

ablyremovably connected. to the cylinder, as y I indicatedin Fig; 3, so thatinpractioe wiienit i's'de'sir'ed to vary the resistance of the piston .13 to the exterior pressure, it is only necessary to remove the inner head of cylinder 12,.

removethe particular spring 14, and intro duce a dlfierent spring of greater or lessre sihency, as desire In operation the valve 3 is opened rid/the valve 7 opened, whereupon the vesse -,1 begins 'to' sink and will continue the plun' e,

until the chamber 2 is filled, whereupont e1 valves-7 and '3 willbe closed. The vessel will probably not, cease its downward travel when the chamber 2 is filled, but ma -con-,

tinue the plunge toan undesirable 'egree,'.

fexcept for the provision of the mechanism above described. Assuming the s ring 14 to be set at a limit above thatto'w 'ch vessel 1 would ordinarily plunge when the chamber 2' is filled, as soon as. the vessel hasdescended to that extent required for, caus ing the pressure of the water on theexterlor of the boat to overcome the resistance of the spring 14 the piston 13 will be caused by at the same time. As soon as the valves such pressure to travel inwardly, and thereeach of the valves 10 will be opened, both the pistons 13 beingof bourse operated are opened air under pressurefrorn the reser voir 8 will enter the chamber 2 and will eject therefrom a certain portion of the water contained therein throhgh the check-valves 16 16. The air will continue to enter the 'cham-.v

her 2 until asu'lficient quantity of water has been ejected to permit the boat. to rise to that level at'which thespring 14 is able to overcome the resistance of the water surrounding the vessel 1 Assoon as the boat 'hasarrived at its level the piston-"13 moves outwardly and draws the valve 10 tb a closed condition, whereupon the supply" of air is cut off and the boatis in condition for traveling at the particular serve that by the rovision of the valves 10 and the piston 13, or automatically governing the o eration the vesse .will plunge, or, in other words, the

depth of the plunge may bepositively pre-. determined. When itis desired to raise the boat again to the surface, air-pressure from any suitable source may be admitted by any ing iston a body, a piston slidably mounted in the cyl- 51 2'. In a submarine boat, a
